Hello Bookworm,
Sorry, but I am another computer dummy who has messed up the multimedia audio controller. I have pasted the Belarc report below. Sony has a support site with all the preinstalled drivers to download but I cannot identify what I need. I really hope you can help! Thank you in advance.
